XenoEnergy XL-050F 1/2 AA 3.6V Lithium Batteries (2 Batteries)

Prompt delivery and product was as advertised.

Ni way toknow how long this unusual battery will last in the remote emergency device, but it tested very strong in my battery tester before I inserted it. Of interest, it was the same battery used by my security company the last time they installed it. The company notified me ultimately that the battery was low and I replaced it. The prior one lasted several years.

I bought ONE of these batteries at pool specialty store for a pool robot cleaner at they charged me $20!! I didn't know any better. I got 2 batteries for less than $9.

We use these for medical equipment.The old ones (OEM) we replaced held up for quite a few years of intensive use in a Hospital environment.As a technician i can highly recommend these batteries.

I have one thing in my house that uses battery and I have not had much luck with batteries from Amazon of this type. However This set is holding up strong

Works as expected. Sorry - no data on how long it lasts, but the build quality seems nice and my temp/humidity is back up and running :-)

I needed a new battery for my Pictar to use with my Apple iPhone. Ordered from Amazon and came in just a few days. Put it in my Pictar and now I am off and running taking pictures once again. The price was right.

After reviewing numerous options, I ordered these. The service was perfect. I received what I wanted, when I wanted it.
